Quartz countertop with double-color pattern and preparation process thereof

Abstract

The invention discloses a quartz countertop with a double-color pattern and a preparation process thereof. The quartz countertop is natural in transition, uniform in board density, excellent in mechanical properties and high in strength and is a repeatedly-usable environment-friendly novel countertop without radioactive pollution and with scratch resistance, fouling resistance and high-temperature resistance. Raw materials of both a material A and a material B for the quartz countertop are composed of quartz sand with a size of 8 to 16 meshes, quartz sand with a size of 40 to 70 meshes, colorless glass with a size of 8 to 16 meshes, colorless glass with a size of 16 to 30 meshes, quartz powder with a size of 400 meshes, high-strength transparent unsaturated resin, a medium-temperature curing agent and a coupling agent. The material A is a main material and further comprises colorless glass with a size of 6 to 8 meshes and mirror glass with a size of 8 to 16 meshes; and the material B is a pattern material and accounts for 1/8 of the usage amount of the material A. The preparation process comprises the following steps: batch mixing via a feed mixer; crushing via screw crusher and remixing; sieving with a screen with a size of 15 mm and mixing; and uniform dispersion of the mud material of the material B into the mud material of the material A, wherein the material B is allowed to be naturally fused into the material A so as to realize double color fusion and present both nebulous impression and spot effect. The quartz countertop provided by the invention has a stable and uniform pattern and a distinct and unique color, can be produced in mass and is applicable as a countertop.

Description

technical field [0001] The invention belongs to the technical field of artificial quartz stone slabs, and in particular relates to a two-color patterned quartz stone countertop and a preparation process thereof. Background technique [0002] In the field of architectural decoration, stone has become one of the main decorative materials due to its beautiful, elegant, and strong decorative characteristics. For a long time, natural marble has rich and natural patterns, and has been widely used because of its natural decorative effect and texture. However, due to limited resources, large-scale paving has problems such as color difference and varying degrees of radioactivity exceeding the standard, low hardness, and easy scratches. , which limits its all-round development to a certain extent. [0003] Artificial quartz stone is a new type of stone material that is made of quartz sand powder as the main filler and unsaturated polyester resin as the binder. Environmental protecti...
